Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465348, here are decompositions:

59 + 31465289 = 31465348
401 + 31464947 = 31465348
521 + 31464827 = 31465348
617 + 31464731 = 31465348
647 + 31464701 = 31465348
839 + 31464509 = 31465348
947 + 31464401 = 31465348
1301 + 31464047 = 31465348

Showing the first eight; more decompositions exist.
